MOP-WRINGER.

Specification of Letters Patent.

Patented Aug. 22, 1916.

Application filed January 11, 1916. Serial No. 71,494.

To all whom it may concern:

Be it known that I, AXEL F. LIFVEN- DAHL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mop-Wringers, of which the following is a description.

My invention belongs to that general class of devices, in which a wringing .machine particularly adapted for use in wringing water out of mops, is also adapted to be supported upon the top of a suitable mop pail or vessel.

The object of my invention is to produce a device for this purpose of simple and economical construction-which at the same time shall be effective in its operation and durable for the purposes for which'it is intended.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a plan view of my improved device in position upon a mop pail; Fig. 2 is a sectionalview thereof taken substantially on line 2-2 of Fig. 1; Fig. 3 is an end view of the device, showing the supporting structure for the rollers, the full lines showing the positions of the parts when the rollers are brought closely to gether, and the dotted lines showing the position when the rollers are separated by operating the controlling lever; Fig. 4 is a rear elevation of the device, showing the means for securing the same upon the vessel.

In the drawings, 1 represents a suitable mop pail, provided with the usual bail 2; 3 represents a preferably metal frame provided with forked parts 4-4, adapted to embrace the edge of the pail, and be secured thereto by means of the thumb screws 55. This portion of the frame is constructed to carry what may be termed a stationary roller 6. This roller is mounted upon a shaft 7, which at one end (the right end, as indicated in Fig. 4, the left end, as indicated in Fig. 1), is inserted in a suitable aperture for a bearing. The other end, which is extended and suitably bent to form a crank for the wringer, has a bearing in a forked opening of the casting, as shown at 8 in Fig. 3, thus permitting the ready positioning or removal of the roller. The free end 9 of the fork 8 may be slightly depressed so as to slightly reduce the entrance, requiring a slight effort to place the shaft in position or to remove it therefrom. The castings are preferably malleable, and a slight tap with a hammer will secure such result. This frame is provided with two rearwardly extending arms 1010, adapted to rest upon the edges of the pail, to aid in supporting the wringer in position. At one side of the frame, as clearly shown in Fig. 1, is formed an aperture or opening 11, while directly opposite thereto on the other side of the frame is shown a suitable and. partially open bearing 12 (Figs. 1 and 3). The two bearings are so arranged that a casting 14, having its ends supported therein, will be permitted a rocking operation. The casting 14 has upon one end a hook 15, adapted to engage the eye or opening 11, and on the other end the extension 16 is adapted to be positioned in the bearing 12. An operating lever 17 extends rearwardly, as clearly shown. As thus arranged the parts 15 and 16 serve as bearings for the casting and permit a rocking therein by means of the operating lever 17. The casting 14 has forwardly, and preferably downwardly extending from each end thereof, arms 18, preferably terminating in open bearings 19. A roller 13 is carried upon a shaft 20, the ends of which are supported within the bearings at 19. These bearings may be slightly closed by a tap of the hammer, as before described, preventing accidental disengagement of the parts. It will thus be seen that the part 14 with its operating lever 17, supported as at 11-12, with the forwardly extending arms 18, form a bell-crank lever carrying the cooperating roller 13, which as the lever 17 is operated, moves the roller 13 with relation to the roller 6. Thus by simply rocking the lever, the mop may be positioned between'the two rollers, if desired, when upon pressing downward upon the lever, the wringer may be operated by means of the crank 7. The preferred operation, however, is clearly shown in dotted lines in Fig. 1. By lifting the free end of the part 14 out of the bearing 12, the part 14 may be swung outwardly and away from the other roller, as clearly shown in said dotted lines in Fig. 1, the hook 15 serving to hold the parts in proper relation to one another. While in this position the mop may be placed in relation to the other roller 6 when the part 14 may be swung back to its normal position shown in full lines in Fig. 1, the end 16 engaging the bearing 12, the lever 17 being lifted to separate the rollers and permit such operation. The lever 17 may then be depressed, forcing the movable roller in proximity to the fixed roller, as before stated.

It is obvious that either of the rollers may be readily separated from the framework at will for cleaning, repairs, or for any other purpose, and as readily assembled. This construction permits a wringer to be of light weight, and at the same time very effective for the purposes for which it is designed.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement or combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is 1. A device of the kind described, comprising a suitable frame adapted to rest upon a vessel, and be supported thereby, and provided with bearings for a roller shaft, and a roller shaft, in combination with a cooperating frame provided with an operating lever, one end of the frame formed to pivot ally and rockingly engage one side of the frame, and the other end to be seated in a substantially open bearing arranged to permit the rocking of the part, said frame being provided with forwardly extending lever arms to substantially form bell-crank levers, each of said lever arms being provided with a bearing for a roller shaft, and a shaft carrying a wringer roller positioned in said bearings substantially as described.

2. A device of the kind described, comprising a suitable frame constructed to rest upon and be supported by a suitable vessel, shaft bearings formed at the ends of said frame, a shaft arranged to be seated in the bearings and carrying a wringer roller, and means for rotating the shaft at will, in com- Copies of this patent may be obtained for bination with a cooperating part formed at one end with a hook loosely engaging one side of the frame, and permitting a rocking movement thereof, the opposite end of the frame provided with a stub extension arranged to be seated in a suitable part in the first frame, an operating lever carried by the part, arms on each end of the part extending forwardly and downwardly terminating in open bearings for a shaft, and a shaft therefor carrying a wringer roller, whereby the free end of the frame may be lifted out of its bearing to swing away from the first roller, and readily replaced again in the first position, the lifting of the operating lever serving to separate the rollers, and the depressing of the operating lever tending to force the operating rollers toward each other. r

3. In a device of the kind described, a wringer frame adapted to rest upon a suit able vessel, and provided with bearings for a roller shaft, means for rotating said roller at will, said frame being provided on one side with an opening eye forming a bearing, and on the other side with an open bearing, in combination with a cooperating part having one end detachably and rockingly engaging the open eye in the first frame, and the other end provided with a stub shaft adapted to be seated in the bearing, forwardly and downwardly extending arms on said part provided with suitable bearings for a roller shaft, a wringer roller having its shaft ends detachably supported in the bearings, and an extending operating lever, whereby the roller carried by the cooperating part, by operating the lever, may be caused to approach or recede from the first roller, or the free end of the part may be detached from the frame and the cooperating part swung about on its pivotal end, serving to separate the rollers and permit the more ready positioning of the mop between the same, substantially as described.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
